Why is energy signal having a finite energy value and 'zero value of power'

AI Thread Summary
Energy signals have a finite energy value and zero power because they exist only for a limited duration, resulting in no average power over time. In contrast, power signals have finite power but infinite energy since they persist indefinitely. The relationship between energy and power is defined by the equations where average power equals total energy divided by time, and energy is the integral of power over time. Therefore, while energy signals are transient, power signals are continuous. This distinction highlights the fundamental differences in how energy and power are measured in signal processing.

Energy signal?

hai..
i want to know why is energy signal having a finite energy value and 'zero value of power'
similarly the power signal have finite value of power and an INFINITE VALUE OF ENERGY

HINT(S):
1) (Average) Power = (Total) Energy / time
2) Energy=\int(Power)dt
3) How much time do you calculate over?
 


hi
it is the general concept irrespective of time

Yes, but a power signal lasts forever. A (finite) energy signal thus has 0 power. A power signal, because of how long it lasts (forever) will also have infinite energy. Unless there's 0 average power.
 

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

Thread 'Where is my curb stop?'

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
